I have read a lot on this topic and it seems there are a million ways to clean records. I just use a discwasher kit and actually don't clean records much unless they have visual residue or dust. Even with a demagnitizer it seems dust is the winner.
Vinyl is weird. There are so many ways to clean, store and
maintain a collection. I pulled out a who record I had as a kid and it was the most nasty piece of shit with visible deep scratches and the record was warped like a potato chip. It sounded excellent. I play the fuck out of my records and treat them the best I can but at 43, my life is (hopefully) half over, so I've gotta play those fuckers like there is no tommorow.

I've tried the VPI record cleaner, the least expensive one. Seemed nice, debated getting one.
I ended up just using Disc Doctor cleaner and brushes. KABUSA.com makes one that you use your own vaccuum cleaner attached to it.

i've been wanting to get either a Nitty Gritty or VPI machine, but can't really afford something like that any time soon. i do have a Spin-Clean, which works nicely for what it is:

You just fill the tray with distilled water, put a capful of cleaning solution on the brushed, and turn the record by hand. Won't clean as thoroughly as an RCM, but definitely makes a difference, especially on second-hand records.
